You got the Neo head, just source a series 2 Na RB30 block, there are plenty around. All your current ecu injectors and ever thing else still works as normal, need a return. The driving ability from the Rb30det to a RB25det is totally different, heaps more torque, plenty of power band and lot faster response.

Im not convinced thats metal man.

Whenever Ive had a metallic issue like that the alloy is generally coarser.

Have you checked everything? If that was from the turbo you would have crazy shaft play, easy thing to check and rule out THB. It may be dirt sucked in from when you had the rocker breathers open.

I don't think it's worth worrying about. It just looks dusty. I think the metal may have gone in during the removal. As they are fairly large bits. So far I've got the top half of the plrnnum off and the turbo off and timing cover off, how do I loosen the belt? Is it just springloaded?

you wont be able to move it side to side...will only lift straight up

as said before there are 3 M6 bolts (10mm heads) 2 at the rear on either side and one on the turbo side front

Massive PITA if you still have the manifolds fitted

there is 2 bolt holes at the rear of the head but there isn't any bolts in them, i un did the bolt from the power steering pump that was into the head but i cant find any more bolts, does anyone have a picture of the bottom of an rb25 neo head? also there is E T written on my intake cam with paint pen.????

ok head is off, apart from the sand in the bores that ended up in there when i lifted the head all looks fine so i guess i just have to keep stripping until i find something wrong.

i find it amusing the stuff nissan stamp into their parts, like my valves all say 5L

definitely a strange question considering all the info you need has been covered before...

Are Rb30's Legal In All States Of Oz?

a man who needs others to do shit for him is a man not able to do shit for himself...

    • Does anyone sell a pipe that's made to go from the Greddy FMIC kit for ECR33 (RB25DET) to the Greddy intake manifold? 
    • Not that I know from experience, but in theory you'd want your gate spring to be as close to target pressure as possible, so you'd go with the higher gate spring?
    • Before I commit to it as I already have the wastegate off the car, would you change it to the 9psi spring instead of the 12, or whack it back on now and try your suggestion?   Edit: Actually I might just swap the spring and see what the logs say after another few pulls, as we know it's still spiking without the Mac valve in the picture so I need more data without the Mac valve trying to combat the issue.
    • Sounds good Hmm suppose the main thing is, how much do you care about this car? The filler doesn't make for a very good water barrier lol. If there was a tiny little bit of rust forming now, that in 3 to 5 years time becomes obvious under the paint (starts to bubble up), would it bother you? 
    • I already have the ability to datalog the voltage... what I can't do is correlate it to what the gauge is showing when I'm looking at the data at a later date. Or something like this. Except getting the oil to 125C+ involves me going 200+kmh at the track so you can imagine this is a little tricky unless I do something like note what the voltage is when I am at the top of 5th gear so I have a point to reference on. Drove car today. O2 still reading richer because hopefully not a leak instead of massive restriction I've introduced. Car really doesn't sound like a LS. It's quite strange. Pulled a bit of fuel out up top. This does potentially explain why my spark plugs looked like the car was running pretty over-rich. If I was tuning it to a ~12.7 which in reality was far richer than that in the past. It will be handy to have the dyno WB to compare my WB to to compare notes that's for sure. At this point I'm happy to just sit in the passenger seat and tune the thing given I've got about 7 million hours on the platform lol.
